The current predominant obstacle for the implementation of energy retrofitting projects at the neighbourhood level is attributable to restricted funding options, which is especially relevant for the expensive renovation of buildings of cultural heritage importance. The first aim of the article is to articulate and identify the main characteristics which influence the funding processes for energy retrofitting historic urban districts. The second objective is to build a comprehensive approach/procedural funding model based on these identified specifics/characteristics. The “energy performance contracting model for historical city centres” (EPCHC) is constructed with procedural processes (steps) associated with the main specific characteristics of urban central districts. The principal attributes which define and influence EPC in historical city centres are “district-level retrofitting”, the “multi-stakeholder approach” and “cultural heritage preservation”. First demonstrated are the benefits of the district level EPC’s “economy of scale”. Secondly, city centres are specific neighbourhoods with several public (municipal, governmental) and private entities, necessitating a particular tailor-made EPC approach is necessary for each stakeholder. Thirdly, the article focuses on the issue of higher retrofitting costs because as a result of historical building status and finding an optimal solution to overcome the conflict between sustainable renovation and cultural preservation. The procedural model for EPCHC in historical city centres offers step-by-step guidelines with suggestions to be followed in order to approach and involve all the various stakeholders. EPCHC could open a new perspective on district green retrofitting and could facilitate municipalities’ decision-making processes upon deciding to retrofit historical central districts.

The road bridge in Cigacice is a very good example of and testimony to the level of knowledge and skills in interwar engineering art. The bridge is almost 100 years old, put to use in 1925, and was designed and manufactured by Beuchelt & Co. in Zielona Góra. The bridge has 10 spans with a parabolic main span, and the supporting structure for the spans is made of steel lattice girders. The object has been strengthened and modernized several times. Currently, renovation works are also being carried out, resulting from identified unfavorable corrosion of the steel elements of the bridge and the concrete bridge slab. The historic steel structure and the bridge supports are being renovated according to the conservation recommendations.

W 2014 roku zrealizowano kolejną sesję badań terenowych we wsiach Białostocczyzny. Najdokładniej zbadano wieś Nowa Wola w gminie Michałowo. Między innymi sporządzono szczegółową dokumentację inwentaryzacyjną fotograficzną i rysunkową trzech drewnianych domów wiejskich w tej wsi. Przeanalizowano specyfikę wnętrz mieszkalnych w tych domach (porównując je z wnętrzami innych domów wiejskich w tejże gminie), dostrzegając wytwory powstałe wskutek połączenia tradycyjnych wzorców estetycznych z nowoczesnymi rozwiązaniami, materiałami i „modami” estetycznymi. Taka synteza wskazuje, iż tradycyjne wzorce kształtowania przestrzeni są niejako wpisane w mentalność miejscowej ludności i trwają pomimo przemian cywilizacyjnych, a być może nawet są wspierane współczesną technologią.

Field surveys were performed in a number of villages in the region of Białystok, N-E Poland, in 2014. The most detailed ones have been done on October 17th, with the research focus on three old wooden houses in Nowa Wola, Michałowo commune. The photographs and detailed drawings have been made. The surveys and their effects have revealed the unique values of home interiors, resulting from the local vernacular tradition enhanced by the contemporary tools, materials and aesthetic patterns. In other words, the vernacular has merged with the modern. Eventually, the spatial results of that fusion proves that vernacular or traditional aesthetic and cultural patterns are fixed in the minds of local people and persist in spite of the technology progress. Moreover, they seem to be even supported by modern tools, technologies and trends.

Students of the Geodesy Faculty of AGH University of Science and Technology in Cracow organized in the years 1974.2001 fourteen scientific expeditions. The aim of each expedition was to perform surveying documentation of an object of the world cultural heritage in Europe, Asia and Africa. The objects covered by inventory were as follows: Koranic school El-Attarine in Fez (Marocco), citadel (Fig.3) in Aleppo (Syria), medieval school Mustansirija College in Bagdad (Iraq), amphitheatre Sabratha (Libya), Templar church in Segovia (Spain), Saint George rotunda in Thessaloniki (Greece), old city buildings (including Kevelaer, Germany), city walls of Kotor (Montenegro), Koranic school Bu Inania in Fez (Marocco), old wooden buildings in Bergen (Norway). Fig. 1, 3, 6, 7 present typical inventory documents . drawings in orthogonal projection, Fig. 2 presents horizontal section. Fig. 5 shows hard and dangerous inventory measurements (leveling measurement on citadel walls in Aleppo (Syria). The inventory works were partly ordered by UNESCO and documentations were handed down to this organization. The students. activity supported restoration of historical buildings in order to preserve them for the future generations.
